ISO7637-2 Pulse1-12V

KES7711A, KES7713B and KES7714 generate test pulses 1 required by the ISO and SAE standards. Test pulse 1 is used to simulate the transient phenomenon that occurs when the power supply is cut off from the inductive load.

■ DC cut time can be set within a range of 1 ms to 200 ms. ■ Since it also outputs positive polarity waveforms whose polarity has been reversed, it supports not only ISO standards but also independent standards of automobile manufacturers as well. ■ Output impedance: Since 20 Ω and 50 Ω can be selected, it supports ISO7637-2.2004 standards and SAE J1113 standards.
